Homework 2

Please turn in your homeworks in one of two forms:

• electronic (in TeX or scanned PDF) via my box
• handwritten (in which case please ensure that you use heavier, good-quality paper. I have to put your homeworks through a scanner to enable me to carry them around; dog-eared thin lined notepaper gets caught and jams the machine.)

Due date: This is due Friday 29th February.

Source: The exercises are all from Zwiebach.
